The complexes K[OsX4acac], X = Cl, Br, I, are prepared by treatment of K2[OsX6] with acetylacetone. The new compounds are characterized by their IR resp. visible and UV spectra which are highly resolved when measured on transparent pellets of the tetraethylammonium salts with KBr at 10 K. The influence of the different halide ligands on the bonding of the acac-group is discussed.

Dibromotetracarbonylmolybdenum, Mo(CO)4Br2, and the dihalotetracarbonyltungsten compounds, W(CO)4X2 (where X = Cl, Br), have been isolated and characterized. These highly reactive compounds are all diamagnetic. The trihalotetracarbonyl anions [M(CO)4X3]- (M = Mo, W) have been isolated as their tetraethylammonium salts from the parent halocarbonyls. These yellow diamagnetic compounds are the first tetracarbonyl derivatives to be prepared from the parent halocarbonyls.
